general purpose relay g7j 3 coil internal circuit ac operating coil the g7j incorporates a bridge rectifier circuit in the ac coil versions that prevents contact chatter or dropout during a voltage drop. this circuit allows the relays to withstand, with no vibration or shock, volt- age drops to the coil of up to 50% of the rated coil voltage for one second maximum. dc operating coil as a rule, either a dc battery or a dc power supply with a maximum of 5% ripple must be used for the operating voltage for dc relays. before using a rectified ac supply, confirm that the ripple is not greater than 5%. ripple greater than this can lead to variations in the operating and reset voltages. as excessive ripple can generate pulses, the insertion of a smoothing capacitor is recommended as shown below. e max.:maximum ripple e min.:minimum ripple e mean:mean dc voltage value when driving the coil with a transistor, check the leakage current and connect a bleeder resistor if necessary. characteristics note: data shown are of initial value. a2 a1 a2 a1 % of ripple = e max. ? e min. x 100 e mean e min. e max. e mean dc fraction ripple rela y smoothing capacitor contact resistance 50 m ? max. operating time 50 ms max. release time 50 ms max. operating frequency mechanical 1,800 operations/hour max. electrical 1,800 operations/hour max. insulation resistance 1,000 m ? minimum at 500 vdc dielectric strength 4,000 vac, 50/60 hz for 1 minute between coil and contacts 4,000 vac, 50/60 hz for 1 minute between contacts of different polarity 2,000 vac, 50/60 hz for 1 minute between contacts of the same polarity impulse withstand voltage 10,000 v between coil and contact with 1.2 x 50 s impulse wave vibration mechanical durability 10 to 55 hz, 1.50 mm (0.06 in) double amplitude malfunction durability no: 10 to 55 hz, 1.50 mm (0.06 in) double amplitude nc: 10 to 26 hz, 1.50 mm (0.06 in) double amplitude shock mechanical durability 1000 m/s 2 (approx. 100 g) malfunction durability no: 100 m/s 2 (approx. 10 g) nc: 20 m/s 2 (approx. 2 g) service life mechanical 1 million operations minimum at 1,800 operations/hour electrical 100,000 operations minimum at 1,800 operations/hour at rated load ambient temperature operating -25 to 60c (-13 to 140f) with no icing humidity operating 35% to 85% rh weight pcb terminal approx. 140 g (4.90 oz.) screw terminal approx. 165 g (5.80 oz.)
